I have had Tarlov cyst surgery with Henderson and I would caution you that you are at great risk for worse pain post surgery with Dr. Henderson. While he states ** that only 10 percent get no improvement after surgery, post-surgery when I told him that my pain was much worse than pre-surgery and constant rather than somewhat intermittent as it was pre-surgery, he emailed to say that 20% get no improvement. I questioned him at a pre-surgery appointment to ascertain if anyone was worse after surgery and he said in only 1 case where his assistant had completed the surgery. He claimed to have done approximately 200 Tarlov cysts before my surgery and upped that figure to 300 in discussion post-surgery 3 months later, claiming at the same time he did 1 per month--none of it adds up. He has no outcome data for his Tarlov cysts surgeries. He is a poor communicator, is not transparent, and disingenuous in my experience. The hospital he is associated with Drs. Community Hospital in Lanham, Maryland is a nightmare--dirty, incompetent staff, fined in 2009 by Maryland Health Board for it's performance and bent more on covering up ongoing incompetence than in improving care. If you've already opted for surgery, which in iteself I would caution you against I hope you had a better experience than mine4.
